PR PRE-ASSEMBLED REMOTE SYSTEMS 

The “PR” system is designed to allow for remote 

location of the condensing unit in applications 

where pre-charged lines would be difficult to run 

or the distance between the evaporator and the 

condensing unit is too great for pre-charged lines. 

All components are installed and wired, but the 

system contains only a holding charge of dry 

nitrogen. Installation involves securing the 

evaporator assembly on the interior of the walk-in 

and the condensing unit in a suitable location. 

Refrigerant lines must be run between the 

evaporator assembly and the condensing unit 

assembly. The system must be leak checked, 

evacuated and charged with refrigerant. The 

electrician must bring power to both the condensing 

unit assembly and the evaporator assembly. On low 

temperature systems the time clock is shipped loose 

and is to be field installed in a convenient location 

outside the walk-in. 

"PR" System Consists Of: 

• Condensing Unit (high side assembly) 

ETL Listed to UL Standard 1995 

• Evaporators (low side assembly) 

• All necessary controls for proper operation 

of condensing unit and evaporators. 

• Time Clock (low temperature 

application) shipped loose. 

Standard Installed Components Include: 

• Thermostatic Expansion Valve 

• Solenoid Valve 

• Temperature Control 

• Drier 

• Pressure Control 

• Weatherproof Housing 

• Low Ambient controls (outdoor) 

• Crankcase Heater (outdoor) 

• Sight Glass 

Continuing product improvement may necessitate 

change of specifications without notice.

REFRIGERATION SYSTEMS 

Pre-Assembled Remote System “PR” Hermetic Air Cooled 

The Pre-Assembled Remote System consists of a 

condensing unit assembly, an evaporator assembly and 

all necessary controls for proper operation. The refrigerant 

lines between the high and low sides are field supplied 

and installed allowing for remote location of the high side.

“PR” Pre-Assembled Remote system 

“PR” Semi-Hermetic Water Cooled 

The “PR” Water Cooled system is designed 

to allow for remote location of the condensing 

unit in applications where pre-charged lines would 

be difficult to run or the distance between the 

evaporator and the condensing unit is too great 

for pre-charged lines. All components are installed 

and wired, but the system contains only a holding 

charge of dry nitrogen. Installation involves securing 

the evaporator assembly on the interior of the 

walk-in, and the condensing unit in a suitable 

location. Refrigerant lines must be run between 

the evaporator assembly and the condensing unit 

assembly. The system must be leak checked, 

evacuated and charged with refrigerant. An 

electrician must bring power to both the condensing 


temperature systems the time clock is shipped loose 

and is to be field installed in a convenient location 

outside of the walk-in. A plumber must then bring 

the water supply and return lines and connect to 

the condensing unit. 



• Evaporator(s)(low side assembly) 

• Pre-Charged Lines Sets (10’, 20’, 30’, 40’) 

• All necessary controls for proper operation 

of condensing unit and evaporators. 

• Time Clock (low temperature application) 

shipped loose 

Standard Installed Components Include: 




• Drier 



• Head Pressure Control Water Flow Valve 

• Water Flow Balancing Valve
